The following query will produce a list of tables that are referenced by one or more Views:

SELECT [table] = s.name + N'.' + t.name  FROM sys.tables AS t  INNER JOIN sys.schemas AS s  ON t.[schema_id] = s.[schema_id]  WHERE EXISTS  (    SELECT 1 FROM sys.tables AS st      INNER JOIN sys.schemas AS ss      ON st.[schema_id] = ss.[schema_id]      CROSS APPLY sys.dm_sql_referencing_entities        (QUOTENAME(ss.name) + N'.' + QUOTENAME(st.name),          N'OBJECT') AS r      INNER JOIN sys.views AS v      ON v.[object_id] = r.referencing_id      INNER JOIN sys.schemas AS vs      ON v.[schema_id] = vs.[schema_id]      WHERE st.[object_id] = t.[object_id]  )
